# Messari API — Daily Crypto Asset Metric Time-Series (1d)

> Messari API — Daily Crypto Asset Metric Time-Series (1d) is a paid API for AI agents from api.messari.io, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-13).

Returns daily historical time-series data for a specified cryptocurrency asset metric (e.g. price_usd) over a given date range.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability messari-api-daily-crypto-asset-metric-time-series-1d-4ee83b8c
```

Example prompt: Pull me Messari's daily price_usd history for bitcoin from 2024-01-01 to 2024-12-31 so I can see how BTC performed last year.

## When to prefer this

Use this endpoint when you need daily-granularity historical metric data for a cryptocurrency asset and want the explicit 1d route. Prefer this over the default time-series route when you specifically want daily bars. Choose this over the 1h, 15m, or 5m variants when lower frequency is sufficient and you want to minimize cost ($0.15/call). Ideal for trend analysis, backtesting, charting, or feeding an agent's memory with macro-level crypto data.

## Known failure modes

- Invalid entityIdentifier (unknown asset slug) — 404 or empty data
- Invalid datasetSlug (metric not available for asset) — 404 or empty dataset
- Date range too wide or unsupported — may return partial data or error
- Malformed ISO-8601 date strings — 400 bad request
- Payment not attached or insufficient — 402 Payment Required
- Rate limit exceeded — 429 Too Many Requests

## How this service works

Get daily cryptocurrency asset metric history via the explicit 1d route.

## Output

An array of timestamp-value pairs representing the daily metric values for the requested asset over the specified date range, e.g. [{timestamp: '2025-01-01T00:00:00Z', value: 94500.00}, ...]
